>>51184143>CharizardAbused Charmander who proceeded to act like a dick then got nice then got left at the valley to train.
>InfernapeWas abused and mocked as a weakling. It makes sense that Pikachu would be on his side rather than getting annoyed.
>GreninjaIf XY had any actual good writing Pikachu would have absolutely been irritated here. Froakie comes out of nowhere. Ash trains it constantly. Focuses super hard on the Bond Evolution shit. Has a 'special bond' with it. How the fuck did Pikachu not feel out of place and shitty over that? There was no friendship between them and Greninja has no personality or backstory to justify Pikachu letting it pass unlike Charizard and Infernape. The faggot just swooped in out of nowhere. And yet Pikachu still ended up having to carry the team against Alain.
>LucarioGreninja done right. Has a special bond with Ash because of their shared aura. Has special powers because of Ash's aura abilities. Has an actual Mega Evolution rather than a donut steel form. Has a personality that made it clash with others (You faggots probably don't even remember Riolu getting in Pikachu's way to battle instead), was born and raised with Ash and it all resulted in Pikachu having an episode where he got frustrated and left for a few days to give Ash a wake up call.
Lucario had actual consequence and meaning with his relationship to Ash and how it impacted Pikachu. And unlike Grenigger, Lucario has an actual personality that changes over the course of the series. Making him an actual character.
